"The first video is exactly what I was looking for! Almost identical to my plans, only using drive shafts instead of belts. A belt still couples the drive train to the drive shaft to absorb vibration induced by the 2-stroke engine. Did I mention mine…"

"Here I am, still a work in progress. Doesn't anyone wonder what a variable pitch quad rotor UAV could do? I've got the whole thing built on paper, and most of the parts to make it happen. I just need about $20k to get a flying prototype…"

"If you need, can use or no anyone who can use the same part you will save per part big time to order 5 or more. For my part I am looking at having done it was around $172 plus shipping. If I order 5 of them it was under $190 before…"

"When I say large blades, I mean blades that serve the same purpose as an airship. So these blimp-blades would be covered with photovoltaic film, would make the variable-pitch quad rotor extremely light, and make it possible to cruise high altitudes…"

"How quickly can the control surfaces be changed? Back in the atomic age, people thought they would get rocket packs and fly around. Now that the general population is more mature in aerodynamics, we can see the value of larger control…"

I've come across this magic number using different sized rotors, props, and engines in large RC helicopters and planes, and also researching horsepower to lift divided by time in several ultralight and light sport aircraft and rotorcraft, and this is a good rule of thumb when developing something that needs to do more than hover or drift in the wind.
